Abstract

Cette invention concerne un procédé de sélection d'un signal, ainsi qu'un système radio cellulaire comprenant des stations de base et un vocodeur qui va coder un signal. Le vocodeur est connecté de manière fonctionnelle aux stations de base par l'intermédiaire de voies de transmission de longueurs différentes. Les stations de base vont recevoir un signal qui a été codé vers l'avant par le vocodeur, puis émettre un signal en sens inverse en direction du vocodeur. Le système radio cellulaire comprend également des dispositifs de sélection qui sont distincts des stations de base. Ces dispositifs de sélection sont disposés de manière à pouvoir choisir au moins un signal à émettre vers le vocodeur parmi les signaux qui ont été reçus par les stations de base en sens inverse. Ces dispositifs de sélection sont également disposés de manière à répartir vers les stations de base le signal qui arrive du vocodeur dans le sens avant.
